Hewett joined the
Indian Civil Service in 1875 and worked in
Agra,
Bulandshahr and
Mathura. He enjoyed travel and hunting in the Himalayan
terai and later wrote on his hunting. In 1898 he was a member of the Indian plague commission. In 1902
Lord Curzon posted him as acting chief commissioner to the
Central Provinces, and he was confirmed in the post in 1903. He was involved in famine relief during 1907 and was
knighted in the same year. He was posted lieutenant governor of the United Provinces of Agra and Oudh in the same year and helped develop industry in the region. He was keen on vocational education and obtained funds for establishing an agricultural college in
Kanpur and organized a trade exhibition in 1910. He was a conservative who preferred Indian peasants as workers rather than be swayed by Western-educated Indians in the
Indian National Congress. He tried to persuade John Morley to go slow on reforms to allow Indians in the civil service. In 1911 he was relieved from his position as governor and sent to Delhi to organize the
coronation durbar of King
George V and Queen Mary. He retired in 1912, but continued to invest in tea and rubber companies across the colonies. He served as the founding chairman of the governing body of the
School of Oriental and African Studies in London. In 1918 he was sent to
Mesopotamia to examine the move to a civilian rule there. He angered
Lord Montagu by speaking to the army officers there against the proposed reform and removal of military rule. He became the
Member of Parliament for
Luton as a Unionist in 1922, but lost it in 1923. He continued to make hunting trips to India. ==Personal life==
